Well, I'll make the most of critiquing your Pokemon. :3 xD
First, replace Dragon Rush with Draco Meteor. It's 140 damage, and it will work very well against anyone. Considering the fact of the loss of Sp. Atk though is something to consider though. I don't really care about stats. My Pokemon can do anything without them. xD
Then, my three options are Flamethrower or Fire Blast. Flamethrower has the perks of having higher accuracy than Fire Blast, with an even hit of 100 damage. However, Fire Blast is 140 (I think, something high like that though) with an accuracy of 85. I've played the game with Fire Blast in my moveset, and I did not regret. So there, if you like accuracy, go Flamethrower. If your fore for attack, go Fire Blast.
Else, this is a minor option, pick Rest. It's good when needed, and you can hold something like a Lum Berry to stop it. Just a minor option.
Good Luck. :)
